Ive been seeing more and more people stating their back button, home and overview buttons are not working unless pressed 100 times on their ultra 25... mine has been not working, I dont want to use gestures. And Im pretty sure that a phone that 1500 dollars should have working navigation without having to press the buttons repeatedly. Im tired of hanging in there for an update that fixes it. What do I do next? Contact Samsung? I mean would you guys accept a phone with horrible navigation?
